Energy Storage integration company FlexGen announced it has been selected by Vistra Energy to establish largest energy storage project in Texas.

Flexgen will design and integrate a 10-MW, 42-MWh energy storage system at the 180-MW Upton 2 Solar Power Plant in Upton County, Texas.

The project is expected to be complete by the end of this year.

"Vistra is leading our country's transformation toward a reliable, low cost, sustainable energy mix and we're thrilled to be supporting its storage strategy," said Josh Prueher, FlexGen CEO. "The power grid of the future will see energy storage integrated on site with solar, wind, and gas generation, and the Upton solar plus storage project is a trailblazing example."
